Are you familiar with the single sided circuit boards? For those that didn’t know what this all about, then you should stick your eyes on this article.
For your information, the most common type is a circuit board that only has printed wiring on one side and all the components are on the other side. A permanent solution to the single-sided circuit board is having it in the shape of a Mobius strip.
The Mobius strip is a surface with only one side, thus it has only one boundary component. The Mobius strip has the mathematical property of being non-orientable. As a result, a model can easily be created by taking a paper strip and giving it a half-twist, and joining the ends of the strips together to form a loop.
Beside that, the ATtiny2313 that has 20-pin device and 17 available output pins, will be used as the main heart in this single-sided circuit board.
To be honest, this project is pretty simple and straightforward, where it only requires you drawing the conductive silver ink throughout the Mobius strip. After that, you’re done with it and can enjoy the using it without any further modification.
